Question

Arrange the following events in the proper order in which they occur during an allergic response.

1 = Individual experiences symptoms
2 = Individual is sensitized to antigen
3 = IgE attaches to mast cells
4 = Antigen binds to IgE

Answer 1

In order is 2, 3, 4, 1

Step-by-step explanation:

It starts when you come into contact with a trigger that you inhale, swallow, or get on your skin. In response, your body starts to make a protein called IgE, which grabs onto the allergen. Then histamine and other chemicals get released into the blood.
